WINDOW STRUCTURE. i i

Application filed April 11, 1921. 7 Serial No. 460,205.

T all whom it may concern Be it known that L'HARRY E. BRADNER, a citizenof the United States of America, residing at Fremont, Sandusky County,Ohio, have invented new and useful Window Structures, of which thefollowing is a specification. v i This invention relates to flexibilityor range of use in closures for openings in buildings.

This inventlon has utility when incorporated in swingable windows,generally referred to as the reversiblefitype. I

Referring to the drawings:

Fig. 1 is a perspective view, with parts broken away, of an embodimentof the invention in a double sash window; Fig. 2 is an enlarged sectionthrough the frame at the pivot point as to the upper sash and at the toprailas to the lower sash;

Fig. 3 is-a fragmentary viewon an enlarged scale of the compound siderail as embodying a primary sash member, a weatherstrip, and a runner; cFig. 4 is. a vertical section through the window and. frame, parts beingbroken away; and I Fig. 5 is a perspective view of the sash cornerassembly blocks with side sash mem bers indicated to show the assemblyrelation.

Building or structure'l is shown as hav may be assembled the closure orwindow offhis'invention. To this end, a simple em bodiment may be asheet metal installation having vertical side frames comprisingstructure opening seat engaging portion 3 carrying by means of bolts orengaging means 4 such number of yokes 5 as may be desirable forrigidity, according to the dimension of thewindow frame. This first seatportion 3 of the frame, carries outer. trim '6. Bolts 7-therethrough maynot only stiffen the positioning of this first frame portion 3 as to theyokes 5, but also mount window seat portion 8 of this frame in as;sembled' position as to the yoke 5. Intermediate of the extent of thissecond seat portion 8 and 'interfitting with Uportion 9 of the yokes5,the seat portion 8 has a channel 10 in which U shaped sash spacing guidestrip 11 may be removably mounted by bolts 12, after the outer sash hasbeen mountedin the frame. Y

The completion of the side frame assembly may occur after-the inner orlower sash is assembled in the frame. To this end, the inner semi-beadedterminus 13 of the first seat portion '3, nesting inyoke seat 14, may beengaged by semi-beadededge 15' of interior finish section 16v of theside frame, and on such interfitting bead portions as a hinge be swunginto position against the window seat providing portion 8, andltheredetachably anchored. by bolts 17 which not only engage the yoke 5, butfurther stiffen the seat portion 8,-by passing therethrough and holdingthe portion 16 .ofthe inner fin ish thereagainst. The side frameassembly is thus complete and of acharacter for ready access, such asmounting of counterweights 18 on cordsv 19 extending over sash cordguides. 20 to be connected to the sash.

At the top, the side frame members may be connected by a boxshaped orhollow structure comprising outer frame -member and trim 21 with innerfinish member or portion 22 mountedthereon by bolts 23.

A ledge 24 of hollow sheet metal structure is shown with a groove 25adjacent the inner side. of the sash seating portionof the ledge. Inthis groove 25 may engage a downwardly projecting rib or flange 26 .of

"In this frame, there is shown as mounted two singlelight sash. Upperlight 31 has top rail 32, bottom rail 33, andside members 34 asitsframe. The light holding side members 34' are a part of compoundgsiderails. The side members 34, on the side thereof opposite the light 31have a pair of seat portions 35 throughout the length o-f the member 34,bounding an intermediate channel 36.1 A second side rail member 37 has achannel 38 opposing the channel 36. This channel 38 has on each side.thereof seat por tions 39 resting for close fitting with the seatportions 35 of the member 3a. The two members 34, 37, of the compoundside rail thus may have a substantial assembly relation. his member 37,on its side remote from the channel 38 has an opening to its hollowinterior.- This permits convenient assembly of nuts ll upon pivot pins42 anchored in the side rail members 34; and protruding through thechannels 36, 38, to anchor a weather-strip as in the member or runner 37of the side rail. This half oval weather strip 43 sealing the jointbetween the compound side rail members 34;, 37, also serves as a catchor lock normally holding the primary sash member 37 of this compoundside rail against swinging. To this end this weather-strip means 43 isnormally urged from the channel 38 to seat in the.

channel-36, by leaf spring 44 about the pivot pin 42, while the remoteportions may be similarly urged into the channel 36 by helical springs45 about guide pins 46 in the channel 38. These springs thus afford ayieldable resistance against any shifting of the light 31 and its frame32, 33, 34, 3e, upon the pair of pins 42 as pivot bearings. Pressureupon this sash exerted suificiently to depress the Weatherstrip as outof the channel 36 and force it b-acli into the channel 38, as the seatportions 35, 39, move out of longitudinal register and the reversiblewindow swings open, does not leave this strip 4:3 in active. The springs44, 45, cause this strip to be held up so snugly against the seatporions 35, that the window is thus held in whatever rocked position itmay be left.

Whenever the window is brought back tovertical position to have thecompound side rails in alignment, at. once, the weathers-trips 43, snapinto window assembly holding relation, and this special window is heldagainst swinging movement. 7

The lower window section having light 4-7, has a frame for this light inthe form of a hollow sheet metal sash having top rail 48, bottom raila9, and side members 50. These side members 50 correspondto the sidemembers 34: of the upper sash, and are completed as a compound side railby runner members 37 and weather strips 4L3.

In the building up of these hollow sheet metal sash, connector blocksare provided. In the top rail 32 of the upper sash, a block 51 may beanchored by swaging, riveting or bolting, to provide a seat to whichside member 37 may be connected. The lower end of the side member 36 mayseat against con.- nector block 52 mounted in bottom rail 33 of theupper sash. The top rail 48 of the lower sash has connector block 53anchored therein, say by bolts 54:, while the side member 50 is boltedthereto by bolts The bottom rail 49 of this lower sash affords seat forconnector block 56 to be nested with the side member 50 in the sashassembly.

The elements of the compound side rails, while hollow or of tubularform, are terminally closed.

The sheet metal type of installation as herein disclosed, may be oflight weight, readily susceptible of quantity production for regularinstallation complete as window and frame. The readily shiftable orremovable inner finish section 16 of the side frame has advantages ofaccessibility to the frame interior, desirable in mounting and adjustingcounterweights. The runner and weather-strip features of the compoundside rails, while herein shown as a part of a specially constructedcompound side rail, it is to be noted may be readily adapted to ageneral type of wooden side rail, by merely cutting down such side railto provide a pivot pin mounting the channel and the seating portionstherealong, while the runner, which may in such instances be of wood ifdesired, is configured as to opposing seat portions and intermediateweather strip channel. Thus, without disfiguring or modifying the windowframe and slide portions, the runners of this disclosure for swingablycarrying a sash, may be incorporated in existing installations, givingthe features of this disclosure a wide field of use.

What is claimed and it is desired to secure by Letters Patent is:

1. A compound side rail for sash including a primary sash member ofclosed figure cross-section and provided with a weather strip receivingchannel, a hollow cross rail, a corner block fitting into the cross railterminating therewith and contoured to seat against inner side of thesash member as extending over the end of the cross rail and means foranchoring the block to said member and rail.

2. A window embodying a pair of sash, runners to which the sash arepivoted for rocking, weather strip means between the runners and sashautomatically frictionally holding the sash in closed position as to therunners, a window frame unit to be engaged by the runners,counterweights for the run ners housed by said unit, a trim closure fora side of the unit hinged to permit access to the counterweights, andmeans for anchoring the trim in closed position adjacent the runners toconfine the runners for straight line travel as coacting with thecounter weights, said trim permitting clearance for sash rocking againstthe resistance of said weather strip means.

3. A. window embodying a pair of sash, a frame mounting one sash abovethe other in window closed position, said sash having side members inpairs one beyond the other, said side members being groovedlongitudinally on the outer sides thereof, runners in the frame opposingeach of said side members, said runners medially of their extent havingpivot pin connection with the side members normally positioning therunners and side members in abutting relation, a Weather strip housed byeach runner and through Which Weather strips the pivot pins extend, andsprings normally thrusting the weather strips into the sash membergrooves between the portions of the members as abutted by the runners.

4. A Window sash having parallel side members, longitudinally extendingoppositely outwardly open grooves in said side members, each bordered bya pair of faces pivotpins extending from the longitudinal centralportions of said grooves, runners abutting the members on the pairs offaces of the members on opposite sides of the grooves and mounted bysaid pivot pins, said runners having channelsopposing the sash membergrooves, Weather strips in the run ner channels between the members andrunner abutting portions and mounted by the pivot pins, and springs inthe runners coacting for maintaining the weather strips thrust towardsthe sash members.
